1.1取力裝置
1.1 power take-off device
國產混凝土攪拌運輸車采用主車發動機取力方式。取力裝置的作用是通過操縱取力開關將發動機動力取出,經液壓系統驅動攪拌筒,攪抖筒在進料和運輸過程中正向旋轉,以利于進料和對混凝土進行攪拌,在出料時反向旋轉,在工作終結后切斷與發動機的動力聯接。
The domestic concrete mixer truck adopts the main truck engine power taking mode. The function of the power take-off device is to take out the power of the engine by operating the power take-off switch, drive the mixing drum through the hydraulic system, and the mixing drum rotates in the forward direction during the feeding and transportation process, so as to facilitate the feeding and mixing of the concrete, rotate in the reverse direction during the discharging, and cut off the power connection with the engine after the end of the work.
1.2液壓系統
1.2 hydraulic system
將經取力器取出的發動機動力,轉化為液壓能(排量和壓力),再經馬達輸出為機械能(轉速和扭矩),為攪拌筒轉動提供動力。
The engine power taken out by the power take-off is converted into hydraulic energy (displacement and pressure), and then output to mechanical energy (speed and torque) by the motor, providing power for the rotation of the mixing drum.
1.3減速機
1.3 reducer
將液壓系統中馬達輸出的轉速減速后,傳給攪拌筒。
Reduce the speed of the motor output in the hydraulic system, and then transfer it to the mixing drum.
1.4操縱機構
1.4 operating mechanism
a.控制攪拌筒旋轉方向,使之在進料和運輸過程中正向旋轉,出料時反向旋轉。
a. Control the rotation direction of the mixing drum to make it rotate in the forward direction in the process of feeding and transportation, and rotate in the reverse direction in the process of discharging.
b.控制攪拌筒的轉速
b. Control the rotating speed of mixing drum
1.5攪拌裝置
1.5 mixing device
水泥自上料攪拌車
它主要由攪拌筒及其輔助支撐部件組成。攪拌筒是混凝土的裝載容器,它是由優質耐磨薄鋼板制成,為了能夠自動裝、卸混凝土,其內壁焊有特殊形狀的螺旋葉片。轉動時混凝土沿葉片的螺旋方向運動,在不斷的提升和翻動過程中受到混合和攪拌。在進料及運輸過程中,攪拌筒正轉,混凝土沿葉片向里運動,出料時,攪拌筒反轉,混凝土沿著葉片向外卸出。攪拌筒的轉動則是靠液壓驅動裝置來保證。裝載量為3~6立方的混凝土攪拌運輸車一般采用由汽車發動機通過動力輸出軸帶動液壓泵,再由高壓油推動液壓馬達驅動攪拌筒,裝載量為9~12立方的則由車載輔助柴油機帶動液壓泵驅動液壓馬達。葉片是攪拌裝置中的主要部件,損壞或嚴重磨損會導致混凝土攪拌不均勻。另外,葉片的角度如果設計不合理,還會使混凝土出現離析。
It is mainly composed of mixing drum and its auxiliary supporting parts. The mixing drum is a concrete loading container, which is made of high-quality wear-resistant steel sheet. In order to automatically load and unload concrete, its inner wall is welded with special shape spiral blades. When rotating, the concrete moves along the spiral direction of the blade, and is mixed and stirred in the process of continuous lifting and turning. In the process of feeding and transportation, the mixing drum rotates positively, the concrete moves inward along the blade, and when discharging, the mixing drum reverses, and the concrete is discharged outward along the blade. The rotation of the mixing drum is guaranteed by the hydraulic drive device. The concrete mixer truck with a loading capacity of 3-6 cubic meters generally uses a hydraulic pump driven by an automobile engine through a power output shaft, and then a hydraulic motor driven by a high-pressure oil to drive the mixing drum. The truck mounted auxiliary diesel engine drives the hydraulic pump to drive the hydraulic Marta with a loading capacity of 9-12 cubic meters. The blade is the main part of the mixing device, which will lead to uneven mixing of concrete if it is damaged or severely worn. In addition, if the blade angle is not designed properly, the concrete will be separated.
1.6清洗系統
1.6 cleaning system
清洗系統的主要作用是清洗攪拌筒,有時也用于運輸途中進行干料攪拌。清洗系統還對液壓系統起冷卻作用。
The main function of the cleaning system is to clean the mixing drum, and sometimes it is also used for dry material mixing during transportation. The cleaning system also cools the hydraulic system.
2 混凝土攪拌運輸車的維護和修理
2 maintenance and repair of concrete mixer truck
混凝土攪拌運輸車作為運輸用汽車,在維護和修理方面必須遵照交通部1990年13號令的規定,執行“定期檢測、強制維護、視情修理”的維護和修理制度。在這個大前提下,再結合混凝土攪拌運輸車的實際情況,做好維護和修理。在日常維護方面,混凝土攪拌運輸車除應按常規對汽車發動機、底盤等部位進行維護外,還必須做好以下維護工作。
As a transport vehicle, the maintenance and repair system of "regular inspection, compulsory maintenance and repair as the case may be" must be carried out in accordance with the provisions of order No. 13 of the Ministry of communications in 1990. Under this premise, combined with the actual situation of the concrete mixer truck, the maintenance and repair should be done well. In the aspect of daily maintenance, the concrete mixer truck should not only maintain the engine, chassis and other parts of the car according to the routine, but also do the following maintenance work.
